VALVE Filed July 7, 1930 INVENTOR. W m BY ATTORNEY UNITED STATES PATENT OFFICE RUDOLF MICHL, OF BRIDGEPORT, CONNECTICUT VALVE Application led July 7, 1930. Serial No. 465,899.

The present invention relates to fiuid fiow control means.

One of the common methods of fiuid fiow control is by means of a needle valve wherein a pin member is movable into and out of engagement with a valve seat formed at an orifice. The fluid jet which emerges from the orifice is however tubular in form because of the fact that the flow must be between the valve seat and pin walls. Itis frequently desirable to have a solid jet of fuel emerge from the orifice irrespective of the size of thelatter and the production of means for obtaining this desired result is one of the objects of my present invention.

A further object of the present invention is the provision of novel controlling means for the orice. A l

Still another object is to so arrange said novel controlling means as to have minimum wear on the closure portions thereof, thereby insuring longevity thereof.

Still a further object is the provison of novel means for unitary control of the said closure means.

And another object is the provision of a device which may readily be manufactured at low cost.

. With the above and other objects in view my invention comprises the novel combination, arrangement and construction of elements to be hereinafter more fully described, shown and defined in the appended claims.

In theaccompanying drawings in which vsimilar reference characters denote corresponding parts Y 1 is alsectional elevation of one form of -my device mounted to a combustion engine and adapted to be used as a fuel inlet control;

Fig. 2is a section along line 2--2 of Fig. 1; and

Fig. 3 is a vertical section of a modified structure showing unitary control means for the orifice closure elements.

Referring lto the drawings, may denote an engine of the Diesel or other injection type which has my controlling device or valve 11 suitably mounted in the fuel inletopening 12 thereof.

My valve proper may comprise a suitably shaped block 13 provided with a longitudinal hole or fuel passageway 14. lThe said hole may be of uniform dimensions throughout and may have an orifice 15 at one end. Suitably arranged in said block and making equal angles with the longitudinal axis of said passageway 14 and diametrically opposite each other are journalling holes 16 and 17 respectively, the diameters of which are at least equal to the diameter of said orifice. The holes 16 and 17 lead into said passageway 14 directly opposite each other. The other ends of said holes 16 and 17 are provided with countersunk portions 16 and 17 for a purpose hereinafter to be specified.

Adapted to be slidably mounted in the yjournalling holes are orifice closure members which may comprise pins 18 and 19 which latter have only sufficient clearance in their respective holes to permit sliding therein. The inner ends of said pin members are beveled as at 18 and 19 so that when the pin members are in their innermost position, the respective beveled faces engage each other and at this time the passageway 14C is completely closed. Sliding of said pin members outwardly causes the bevelled face to spread apart and expose correspondingly more and more of the passageway. Suitable means for continuously urging said pin members into their outermost positions, as springs 20 in the countersunlr portions of said journaling holes may be provided. To slide the pin members, bolts 21 threadedly adjustable and located near free ends of said countersunk holes may be provided. Each of said pin members may be individually adjusted by its respective bolt 21.

It will be noted that the exposure of the passageway is always from the center thereof outwardly and consequently irrespective of the amount of exposure, the fluid jet emerging from the orifice will always be solid.

It is desirable in most cases to have common means for controlling the two pin members in order that they may be moved simultaneously.

In Fig. Sis shown one way of accomplishing this result. The structure in general is essentially the same as that of the first modification except, that the upper face of block 13 is provided with an annular groove 22 into which the heads 182 and 192 of said pins project. The said bloclr is also provided externally with a threaded portion 28 and a eaplilre member 24; having' a threaded portion is adapted to screw thereon. The inner face of said cap member may be provided with an annular rib member 26 which latter is adapted to ride in said groove 2Q. on said pin heads. Thus by screwing said cap member inwardly or outwardly corresponding simultaneous motion of said pin members is obtained, thereby respectively closing` or opening the passageway. n

Suitable means'for attaching either of the devices to an engine as for instance by the threaded ends 13a on each of said blocks may be employed. Likewise the free ends of said fuel passageways 14 may have a threaded countersunlr portion Q7 into which the fuel leads 28 may be screwed.

My device may be modified in many ways Y and is not limited in its application to valves for engines, but may be used universally for duid control purposes.. Likewise it is not necessary that two pins only need be employed for orifice control as three or more v pins may also be employed provided the engaging ends thereof are correspondingly bevelled.

My invention may be modified in various other ways without departing from the spirit thereof and I do not wish to be limited to the details shown and described.

What I claim is 1. A fluid controlV valve comprising a block having a fluid passageway therethrough and means for producing a solid fluid jet of controlled size, said means comprising slidable plunger members shaped at their lower' ends to enga-ge each other, supported in journalling holes in said bloclr` and adapted to pro ject into said passageway and close off the latter and means for moving said plunger members into and out of engagement with each other.
